Grange
Household income in Grange sits in the 98.6th percentile nationally, yet the median house price of $639,000 stays well below comparable inner-city Brisbane premium markets, a gap that makes the suburb unusually affordable for the wealth it holds. The area scores decile 10 on all four SEIFA indexes (IRSAD, IEO, IER, IRSD), the top advantage tier in Australia. University qualifications reach 59.6%, which is 29.5 points above the national figure, and the population skews younger at a median age of 37, three years below national. Detached houses dominate at 82.2% of dwellings across a compact 1.75 km2, an established family profile rather than a high-rise one.

The $639,000 median house price is modest for a decile 10 suburb only 5 km from Brisbane's CBD, and it pairs with a family-oriented stock. Separate houses make up 82.2% of dwellings while apartments are just 8.3%, so buyers compete for traditional homes rather than units. Four-bedroom-plus homes account for 48.0% and three-bedroom 33.5%, confirming the larger-household character with an average size of 2.9 people, 0.4 above national. Monthly mortgage repayments average $2,600, producing a mortgage-to-income ratio of just 18.3%, far below the 30% stress threshold because incomes are so high relative to prices. Mortgage holders (44.9%) outnumber outright owners (30.7%), a sign of active, recent buyers rather than a settled, debt-free base.

For Investors
A 24.4% renter share and weekly rent of $460 give landlords a moderate tenant pool, and against the $639,000 median that rent implies a gross yield near 3.7%, healthier than most premium inner-Brisbane suburbs. The vacancy rate of 4.4% is slightly loose rather than tight, so rent growth depends on demand support more than scarcity. Rent climbed 19.5% over the recent period, and overseas migration adds about 60 residents a year while internal migration removes 28, leaving net inflow as the primary growth driver. Development activity is low at 36 applications in 12 months, mostly building work and operational filling rather than new apartment supply, which limits future stock and supports existing values. With annual population growth forecast at 0.95%, the case rests on steady yield plus capital growth more than rapid expansion.

Demographics
The median age of 37 is 3.0 years below the national figure, younger than most decile 10 suburbs and consistent with a family rather than retiree profile. Overseas-born residents reach only 16.9%, which is 4.7 points below national, so the area is more Australian-born than the typical inner-city suburb. Ancestry leans Anglo-Celtic, led by English (2,046), Irish (881) and Scottish (624), and the top non-English languages are Italian (26), Mandarin (16) and Portuguese (13), all small in number. University qualifications at 59.6% run 29.5 points above national. Couples with children (2,212 families) far outnumber couples without children (719, or 18.0%), and the average household size of 2.9 is 0.4 above national, reinforcing the established-family character of the suburb.

Tenure
Tenure tilts toward mortgaged owners: 44.9% carry a mortgage, 30.7% own outright and 24.4% rent. Mortgage holders outnumbering outright owners points to a market of active buyers rather than long-settled, debt-free residents. The stock is overwhelmingly detached at 82.2% separate houses, with apartments at 8.3% and semi-detached at 9.4%, which keeps the suburb a low-density family enclave at 2,631 people per km2. Four-bedroom-plus dwellings reach 48.0% and three-bedroom 33.5%, so larger homes dominate. The $639,000 median against household income in the 98.6th percentile gives a low mortgage-to-income ratio of 18.3% and rent-to-income of 14.0%, both well below the 30% stress line, a divergence that reflects how strong local incomes are relative to property costs.

Economy & Employment
The local workforce concentrates in knowledge and care sectors: Healthcare leads at 21.0% (418 workers), Professional/Tech follows at 17.3% (345) and Education at 11.1% (222), with Public Admin at 8.2% and Finance at 6.7%. By occupation, Professionals (1,007) and Managers (514) account for the bulk of jobs, which aligns with the decile 10 IEO score for education and occupation. Unemployment is low at 3.4% and the full-time employment rate is 66.8%, with participation at 69.8%. Real incomes grew 20.1% over the decade. All four SEIFA indexes read decile 10, the top advantage tier, with no anomaly between them because high incomes, professional jobs and detached ownership reinforce each other rather than pulling in different directions.

Transport to Work
Car use is high at 79.9% of commuters, above the national pattern, while public transport carries 9.6% and active travel just 5.8%, typical of a low-density detached suburb 5 km from the CBD. The area earns decile 10 on IRSAD, the top advantage tier nationally, and decile 10 on IRSD for relative disadvantage, meaning very few residents face deprivation. Volunteering runs at 21.4% and only 2.6% (118 people) need daily assistance, low for any age group. Rent-to-income at 14.0% and mortgage-to-income at 18.3% keep both tenants and buyers comfortable, well below the 30% stress threshold. No schools are recorded inside the 1.75 km2 boundary in this dataset, so families rely on institutions in neighbouring suburbs, a practical trade-off for the compact footprint.

Population Forecast
+0.95%/yr
(+47 people/yr)
EstablishedGrange is a steady grower rather than a boom market: annual population growth is forecast at 0.95%, about 47 people a year, and the 10-year change of 11.1% classifies it as an established suburb accelerating from a low base. The current population near 4,942 is projected to reach about 5,201 by 2031 under the medium trend. Overseas migration of roughly 60 a year is the primary driver, offset by net internal outflow of 28. The gentrification stage reads early signs, with population up 14% since 2011 and growth accelerating from 2% to 12%, while affordability improved from 43.0% in 2011 to 34.8% in 2021. The young-resident share fell only 0.7 points, so the family profile is holding rather than aging out.

How to read these comparisons
Phrases like "above the national average" reference the unweighted median across Australian suburbs with more than 1,000 residents, not population-weighted national figures. Suburb-level medians are more useful for ranking suburbs against each other; ABS census headlines are population-weighted (so dominated by Sydney and Melbourne) and can read very differently.
Current baseline (refreshed 2026-05-10): median age 40, university-educated 30.1%, born overseas 21.6%, average household size 2.5 people.
Data sources: ABS 2021 Census (demographics, income, tenure), state Valuer-General (house prices), Department of Jobs SALM (unemployment), ACARA (school ICSEA), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
